Accuracy

When you sharpen a blade in the Warthog, the blade’s edge serves as a reference. Your sharpening angle remains the same, sharpening sessions after sharpening session.

If there is variation, it’s negligible.

When you sharpen a blade with the Lansky Deluxe, the blade’s spine serves as reference point. This means that, if you don’t secure the knife to the guide at the exact spot you tightened it to with your previous sharpening session, you’ll have to resharpen the knife completely.
